Samar da wutar lantarki ta hasken rana a Japan a cikin 2030, shin ranakun rana za su samar da mafi yawan wutar lantarki na rana?

A ranar 30 ga Maris, 2022, Tsarin Mahimman Bayanai, wanda ke binciken ƙaddamar da tsarin samar da wutar lantarki (PV) a Japan, ya ba da rahoton ainihin ƙimar da ake tsammani na gabatarwar tsarin photovoltaic ta 2020. A cikin 2030, ya buga "Hasashen Hasashen Gabatarwar samar da wutar lantarki ta photovoltaic a cikin kasuwar Japan a cikin 2030 (bugu na 2022)”.

Dangane da alkalummanta, ƙaddamar da ƙaddamar da tsarin photovoltaic a Japan ta 2020 shine kusan 72GW, dangane da fitarwar halin yanzu kai tsaye (DC).A cikin "harka girma na yanzu" don kula da adadin gabatarwar DC na yanzu na kusan 8 GW a kowace shekara, hasashen yana da 154 GW, tare da canjin halin yanzu (AC) na 121 GW a cikin FY2030Note 1).A daya hannun, "Gabatarwa Acceleration Case", wanda ake sa ran zai inganta sosai da kuma ci gaba da shigo da yanayi, yana da tushen DC na 180GW (AC tushe na 140GW).

Af, a cikin "Shirin Basic Makamashi na Shida" wanda Ma'aikatar Tattalin Arziki, Ciniki da Masana'antu ta tsara a ranar 22 ga Oktoba, 2021, adadin wutar lantarki da aka gabatar a Japan a cikin 2030 shine "117.6GW (AC a matakin buri).Base)".Ma'aikatar Tattalin Arziki, Ciniki da Masana'antu matakin "buri" ya kusan dacewa da saurin gabatarwa na yanzu.

Koyaya, waɗannan ƙimar fitarwa na tsarin PV na tushen DC ana ƙididdige su lokacin da wasu yanayi kamar zafin rana da kusurwar rana suka cika.A zahiri, sau 7 (×0.7) shine kololuwar samar da wutar lantarki.Wato, nan da 2030, ana sa ran za a iya samar da kusan GW 85 a ƙarƙashin yanayin girma na yanzu da tsakar rana a cikin yanayin rana, da kuma kusan 98 GW a ƙarƙashin haɓakar gabatarwar (duka tushen AC).

A gefe guda, kololuwar buƙatun wutar lantarki na Japan na baya-bayan nan ya kusan 160GW (a madadin halin yanzu).Kafin babbar girgizar kasa ta Gabashin Japan a watan Maris na 2011, ta kasance kusan 180GW (daidai da na sama), amma tare da ci gaban tsarin ceton makamashi na zamantakewa, haɓakar tattalin arziƙin ya ragu, kuma canjin tsarin tattalin arziki ya ci gaba, kuma samar da wutar lantarki ya ragu.Idan bukatar wutar lantarki a shekarar 2030 ta kusan daidai da yadda take a yanzu, za a iya kirga cewa 98GW/160GW = 61% ko fiye na yawan bukatar wutar lantarkin kasar Japan na iya biyan wutar lantarki da rana da rana.
